The prevalence of oral squamous cell carcinoma with oral submucous fibrosis.

OBJECTIVE: The objective of the study was to find out the prevalence of oral squamous cell carcinoma (OSCC) with oral submucous fibrosis (OSF) in patients with OSF. MATERIALS AND METHODS: Of 48,757 patients, we found 300 OSF subjects. Three hundred patients of OSF were checked for OSCC. Both OSF and OSCC with OSF (OSCCwOSF) were diagnosed histopathologically. The prevalence of OSCCwOSF was calculated. Descriptive analysis was done. Chi-square test and t-test were calculated for proportions and mean, respectively, to check any difference among OSF and OSCCwOSF groups. Age-specific relative risk was calculated in OSF and OSCCwOSF groups. Multiple logistic regression analysis was done among odd ratios of the different variable between OSF and OSCCwOSF groups. RESULTS: The prevalence of OSCCwOSF among OSF was 13.7% over a period of 1 year. The mean age of OSCCwOSF group was 43.95 ± 10.22 years in comparison to the OSF group that was 35.51 ± 11.26 years (P < 0.00). The mean habit duration was significantly less in the OSF group when compared to OSCCwOSFgroup for mishri (P = 0.002). Age-specific adjusted relative risk of OSCC in OSF patient increases from 0.33 (18-34 years) to 3.86 (≥65 years). CONCLUSION: It could be concluded that a 13.7% prevalence rate of OSCCwOSF in OSF patients should alert the clinician. Clinicians should, therefore, anticipate OSSC in OSF patients. This awareness could lead to the early diagnosis and management of such OSCC.

Attitude and awareness of general population towards radiation hazards and safety: An institutional study.

CONTEXT: Radiological investigations play a pivotal role in the diagnosis and treatment of a wide range of procedures. AIM: To assess the knowledge regarding adverse consequences of radiological examination and encourage awareness regarding radiation protection amongst general public. SETTINGS AND DESIGN: A questionnaire-based cross-sectional study conducted amongst patients visiting the dental outpatient department. MATERIALS AND METHODS: 1,000 adult male and female patients within the age of 20-70 years who visited the outpatient department during May-July 2017 were included in the study. STATISTICAL ANALYSIS: Comparison of frequencies of responses to each item with age and gender was done using chi square test. For all statistical tests, P < 0.05 was considered to be statistically significant, keeping α error at 5% and ß error at 20%. RESULTS: 85.3% participants had visited a hospital earlier and 69.3% had undergone the procedure of an X-ray earlier. Out of those patients, only 24.7% of the participants had any knowledge about the equipment or the procedure while taking a radiograph. 5.2% of the participants were given any safety measures during the radiological procedure. 14.4% had knowledge of the risks and hazards associated with radiation. CONCLUSIONS: This short study showed that there is a need for educating the general population about the hazards and risks associated with radiation exposure.
